a; the shear stress imparted by the sub-projectile, τ; and the
component of pressure in the axial (z) direction. We proceed by initially nding an expres-
sion for the volume of the sabot free body. Details of this derivation are found in Ref. [6].
The incremental volume of the sabot can be shown as follows:
